Android HTTP 401-在MVVM模式中使用RxJava2和Reformation2清空recyclerview,android,android-recyclerview,retrofit2,rx-java2,android-mvvm,Android,Android Recyclerview,Retrofit2,Rx Java2,Android Mvvm,我对MVVM模式和使用RxJava2和2调用API非常陌生。我正在尝试从Unsplash API调用API 我不知道我该怎么做，我看过很多教程，但没有解决问题的办法这里是我提供APIService和OkHttpClient和改造的地方： @Provides @Singleton fun provideHttpLoggingInterceptor(): HttpLoggingInterceptor { val interceptor = HttpLoggingInterceptor()

我对MVVM模式和使用RxJava2和2调用API非常陌生。我正在尝试从Unsplash API调用API 我不知道我该怎么做，我看过很多教程，但没有解决问题的办法

这里是我提供APIService和OkHttpClient和改造的地方：

            addInterceptor(httpLoggingInterceptor)

    }
    return okHttpClient.build()

    return retrofit.create(PhotoService::class.java)

查看unsplash的文档，似乎需要将查询作为查询参数传递给

client\u id

，如下所示

https://api.unsplash.com/photos/?client_id=YOUR_ACCESS_KEY

用户身份验证api可在

https://unsplash.com/oauth/

查看更多信息。

您没有访问api的权限。您需要发送一些访问令牌。检查其文档。
